generate_test_cases

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses that the tool saves generated test cases to the project store (write behavior) and returns the full list, providing useful context beyond mere generation. It doesn't mention side effects like overwriting or project existence, but the disclosed behaviors are sufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three concise sentences, each serving a purpose: action, coverage scope, and side effect. No redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having no output schema, the description clearly explains the return value ('returns the full list') and the persistence behavior. The parameters are well-documented in the schema, and the tool's purpose is clear. It's sufficiently complete for an AI agent to select and invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already provides 100% coverage with descriptions for all four parameters. The description doesn't add additional semantic meaning beyond the schema, other than implying that the 'description' parameter is central to the analysis. This is adequate per the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool auto-generates comprehensive test cases from a feature/function description, with a specific verb ('auto-generate') and resource ('test cases'). It also lists coverage areas (happy path, edge cases, etc.) and distinguishes from sibling tools like add_test_case (manual) and list_test_cases (retrieval).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when test cases need to be generated from a description but doesn't explicitly mention scenarios where this tool should be avoided or alternatives should be used. It lacks explicit 'when-not' guidance or references to sibling tools like add_test_case for manual entry.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
